Mattias H, the next step is to fully commit bisect from kernel 4.2.0-27
to 4.2.0-30 in order to identify the last good kernel commit, followed
immediately by the first bad one. This will allow for a more expedited
analysis of the root cause of your issue. Could you please do this
following https://wiki.ubuntu.com/Kernel/KernelBisection ?

Please note, finding adjacent kernel versions is not fully commit
bisecting.

After the offending commit (not kernel version) has been identified,
then please mark this report Status New.

Thank you for your understanding.

A start job is running for Detect the available GPUs and deal with any system 
changes

Maybe this is an issue for ubuntu-drivers-common?

[Bug 1549979] Re: xorg freezes upon system boot with kernel 4.2.0-30

[Christopher M. Penalver]

Mattias H, in order to allow additional upstream developers to examine the 
issue, at your earliest convenience, could you please test the latest upstream 
kernel available from http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D ? 
Please keep in mind the following:
1) The one to test is at the very top line at the top of the page (not the 
daily folder).
2) The release names are irrelevant.
3) The folder time stamps aren't indicative of when the kernel actually was 
released upstream.
4) Install instructions are available at 
https://wiki.ubuntu.com/Kernel/MainlineBuilds .

If testing on your main install would be inconvenient, one may:
1) Install Ubuntu to a different partition and then test this there.
2) Backup, or clone the primary install.

If the latest kernel did not allow you to test to the issue (ex. you couldn't 
boot into the OS) please make a comment in your report about this, and continue 
to test the next most recent kernel version until you can test to the issue. 
Once you've tested the upstream kernel, please comment on which kernel version 
specifically you tested. If this issue is fixed in the mainline kernel, please 
add the following tags by clicking on the yellow circle with a black pencil 
icon, next to the word Tags, located at the bottom of the report description:
kernel-fixed-upstream
kernel-fixed-upstream-X.Y-rcZ

Where X, and Y are the first two numbers of the kernel version, and Z is
the release candidate number if it exists.

If the mainline kernel does not fix the issue, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-X.Y-rcZ

Please note, an error to install the kernel does not fit the criteria of
kernel-bug-exists-upstream.

Once testing of the latest upstream kernel is complete, please mark this
report's Status as Confirmed. Please let us know your results.

Thank you for your understanding.

Sure, np. The problem still exists. No change.

[Bug 1549979] Re: xorg freezes upon system boot with kernel 4.2.0-30

[Christopher M. Penalver]

Mattias H, thank you for reporting this and helping make Ubuntu better.

As per
http://h20564.www2.hp.com/hpsc/swd/public/readIndex?sp4ts.oid=5428311=8=4192
an update to your computer's buggy and outdated BIOS is available
(1.35). If you update to this following
https://help.ubuntu.com/community/BIOSUpdate does it change anything?

For more on BIOS updates and linux, please see
https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette
.

Please note your current BIOS is already in the Bug Description, so
posting this on the old BIOS would not be helpful. As well, you don't
have to create a new bug report.

Once the BIOS is updated, if the problem is still reproducible:
1) Please provide the output of the following terminal command (not perform an 
apport-collect):
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date
2) Please make a comment specifically advising on if there was an improvement 
or not.
3) Please mark this report Status New. If it's not reproducible, please mark 
this as Invalid.

Thank you for your understanding.
